Thanks for the reply. I assume I'd have to know the people beforehand? As in there is no system where people willing to give and people in need of transportation can interact?

When the game organizer made a thread about a game, other players post "in" "out" or "maybe".
If you need a ride, you can post something like "Maybe - In if I can get a ride", and include your location, also good to state you are willing to split the gas cost, etc. Someone else going on the same direction may contact you. You don't have to know each other beforehand - You guys are both airsofters! That's means a lot already.
